Evaluation of adnexial masses: pozitive predictive value in US, CT, and MRI

Purpose: Cross sectional imaging technigues more widely available in the recent years for evaluation of pelvic and tubo-ovarian lesions. We discussed the primary contribution of these methods in the diagnosis of uterine masses in the patients with tubo-ovarian lesions. Materials and Method: IVe present 41 tubo-ovarian lesion with pathologic correlation. Transabdominal sonography, enhanced and nonenhanced CT seans were performed in ali cases. Moreover sagittal and axial T1-weighted as well as T2- vveighted, and fat-saturated unenhanced and gadolinium- enhanced MR images of the pelvic region. kVe compared our radiologic findings with histopathological results. Results: Three of 41 cases had corpus luteum eyst, 10 had eystadenoma, 7 had ovarian carcinoma, 7 had dermoid eyst, 4 had endometrioma, 3 had abcess, 2 had eyst hydatid, and 1 had ovarian fibroma on histopathological examination. Correct diagnosis was established in 33 (80%) out of 41 lesions with US, in 29 (80%) out of 36 lesions with CT scan and in 33 (83%) out of 40 lesions with MRI. Correct diagnosis was established in 33 (83.3%) out of 36 lesions with US, in 29 (77.7%) out of 36 lesions with CT scan and in 33 (86.1%) out of 36 lesions with MRI. Conclusion: Because of ability to detect invasion and in defining the extent of disease, MRI is better than sonography, and CT, and appears to be the modality of choice for evaluated of the pelvic masses. Although US pas potantial advantages and limitations, it should be preferred as the first method of searching for pelvic pathologies.
